Participants

Reaction Steps

Benzyl 3-oxopiperazine-1-carboxylate (400 mg) and 3-(bromomethyl)pyridine hydrobromide (647 mg) were mixed with DMF (8 ml), and sodium hydride (55% suspended in oil) (194 mg) was added thereto at 0° C., followed by stirring at room temperature for 3 hours. Water and CHCl3 were added to the reaction mixture at 0° C., and the organic layer was washed with water and saturated brine, dried over anhydrous sodium carbonate, and concentrated under reduced pressure. The obtained residue was purified by basic silica gel column chromatography (EtOAc/hexane) to obtain benzyl 3-oxo-4-(pyridin-3-ylmethyl)piperazine-1-carboxylate (345 mg).
